三相四桥臂逆变电源控制策略
The Control Strategy for Three-Phase Four-Leg Inverter
摘要
Abstract
The traditional three-phase four-wire inverter uses the structure with three-phase three-leg, and the fourth wire constitutes the neutral formed transformer. A novel three-phase four-leg inverter is presented in this paper by adding the fourth leg to form neutral point instead of NFT to reduce the volume and weight and cost. This paper suggests a 3D-SVPWM control strategy and adds feed-forward compensation method for further improvement. The simulation result shows that this control strategy is feasible to provide the reliable theoretical basis for the new inverter to deal with unbalanced load and improve the utilization rate of DC bus voltage.关键词
